Membrane Inlets for on-Line Liquid-Phase Mass Spectrometric Measurements in Bioreactors
A simple type of sterilisable membrane-covered inlet to a mass spectrometer consists of silicone tubing covering small circular holes in a metal tube. An inlet of this type allows continuous measurements of the concentrations of dissolved gases and hydrophobic compounds such as alcohols in bioreactors. The measuring system has been used to follow ethanol, oxygen and carbon dioxide during the production of yeast biomass from molasses on the laboratory and industrial scale.
